A liquid discharge apparatus includes a discharge section, a charge supply source, first and second signal paths, and a connection path selection section. The connection path selection section uses the first or second signal path to electrically connect a piezoelectric element and the charge supply source. The charge supply source include a number n (where n is a plurality) of capacitive elements, and a switching section configured and arranged to switch between a series state where the n capacitive elements are electrically connected in series and a parallel state where the n capacitive elements are electrically connected in parallel. In the series state, a given first point out of connection points between the n capacitive elements is connected to the first signal path, and a second point higher than the first point out of the connection points of the n capacitive elements is connected to the second signal path. |
